Subject: [PATCH] config/debuginfod.m4: Use PKG_CHECK_MODULES

Use PKG_CHECK_MODULES to set debuginfod autoconf vars. Also add
pkg.m4 to config/.

ChangeLog:

        * config/debuginfod.m4: use PKG_CHECK_MODULES.
        * config/pkg.m4: New file.
        * configure: Rebuild.
        * configure.ac: Remove AC_DEBUGINFOD.

ChangeLog/binutils:

        * Makefile.am: Replace LIBDEBUGINFOD with DEBUGINFOD_LIBS.
        * Makefile.in: Rebuild.
        * configure: Rebuild.
        * doc/Makefile.in: Rebuild.

ChangeLog/gdb:

        * Makefile.in: Replace LIBDEBUGINFOD with DEBUGINFOD_LIBS.
        * configure: Rebuild.
